CN825R from ShangHai Consonance Elec, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	/MR	input	Active-low manual reset input. Pulling this pin low triggers a reset pulse on both reset outputs. Internally pulled up to VCC via a ~50 kΩ resistor (38-62 kΩ), so it can be left floating, driven by CMOS, or driven by open-drain/open-collector logic. Minimum pulse width 1 µs; MR-to-reset delay ≤500 ns.
2	GND	power_in	Ground / negative supply return for the device.
3	/RESET	output	Active-low reset output. Driven low when VCC is below the 2.63 V reset threshold, when /MR is low, or when the watchdog times out. After the condition clears, /RESET stays low for at least 140 ms (typ. 200 ms) before returning high. VOL = 0.3 V max at 3.2 mA sink (150 µA at VCC = 1.1 V).
4	VCC	power_in	Positive supply input, 1.1 V to 6.5 V operating range. This pin is continuously monitored and compared to the internal 2.63 V (CN825R) reset threshold. Supply current 2.7 µA typ. below threshold, 16 µA typ. above threshold. Abs max 6.5 V, 20 mA.
5	RESET	output	Active-high reset output. Driven high when VCC is below the reset threshold, when /MR is low, or when the watchdog times out. After the condition clears, RESET stays high for at least 140 ms (typ. 200 ms) before returning low. VOH = VCC−1 V min at 1 mA source (1.0 V min at VCC = 1.1 V, 8 µA).
6	WDI	input	Watchdog input. If WDI is held high or low for more than the watchdog timeout (typ. 1.6 s, min 0.95 s, max 2.25 s) without a logic transition, the watchdog expires and asserts both reset outputs for ≥140 ms. Input high threshold 0.75·VCC, low threshold 0.25·VCC; input current ±50 nA; minimum detectable pulse width 50 ns.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn825r.step`	97 KB	You want the bare part, or you mark your own boards.
`cn825r-etched.step`	1.6 MB	You want the part with `CN825R` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 373 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
